windows cannot recognize the specified device

I get this error message when I try to open anything on my desktop, including my antivirus program. I can open Internet Explorer but not Mozilla Firefox. Cannot open Microsoft Money or any of my other programs. The message is Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item other programs.

try tapping f8 on bootup and select safe mode with networking. Download and run Malwarebytes:http://www.filehippo.com/download_m...in full scan mode and fix all it finds. Then reboot to normal mode and see if the problem still persists
